To all whom t may concern.' n

Be it known that I, Ti-ioiris Frm GERALD, a citizen ofthe United States ot'` tion through the lock;

Figure 2 is a horizontal section on line 2-2 of Figure l;

Figure 3 is a plan view.

A is a casing which is connected at its opposite ends with the conduit B leading from the fuel supply tank and the conduit C extending to the carburetor. The casing A is orined with a series of valve seats D valves E, said valves having steins F which pass upward through packing glands G', and'` having springs H which yieldably hold them to their seats. are angularlirr arranged intersecting passages which extend in a zigzag course between the several valve seats D, said passages being' preicerably it will be impossible to'look through the casing roni one end to the other.

The valve stenis F pass upward into a casing K which has a glass or transparentA cover L and visible through this `cover are indicators M. rlhe valve steins are further provided with handles N between the `casing K and Athe casing A so that any one oi' said stems can be rotativeiyT adjusted by ineans o' the handle. I i

i/Vith the construction as described, the tuel passage may be blocked by theturning oit` one or more of the valves E so as to disi locks for i Figure l is a vertical longitudinal ser:`

therein for engaging rotary conical plug from a solid piece ot instal for registration with said Zig-zag passag stcnis for operating said valves, indicators "d., h 11 .i a connect :ioni the angling passages. in this position it npossibie Ytor anu one to dererini .what adjustment is required to bring the ialie again into registration, forr the valve itself; is concealed. iIow-evei',the indicators ML are numbered and anyonefiia# iniliar with 'the coiiibiii 1 tion can readily rthe valves so a s to forni A itheless, it would be impossible ioi one not knowing the coni bination to soset the valves, for all inust be properly adjusted before the fluid is per `ii'iitted to i'iow and experimenting on one will be or no avail if another valve 1s out oi registration. rlilhus, the locking is ei:-

ectual, but at any time a person knowing kthe combination can quickly adjust the valves to open position.

1What .i claim niy invention is: n i1.. A gas lool; comprising a casing formed troni a solid piece of metal and having a passage therethrough, a series of valves in said casing for obstructing said passage, each. valve i being port-ed to opeii coininunication with said passage when properly set, indicators secured to said valves, a casing inclosing lsaid indicators and having a transparent wall therein for viewing said lindicators and an index cooperating with said indicators to facilitate the setting of said valvesv iii proper registration. gas lloclrcomprising a casing formed rroni a solid piece oi nietal und having a bored out zig-Zag i 'Lesage therethrough with is valv( is at intermediate points in said passage, a series oic `rotary plug valves engaging.j `said seats and adapted to open communication through said zig-zag passages, steins for operating said valves, indicators at the upper ends of said steins, a casing having a transparent top for enclosing said indicators and permitting they viewing of the saine, and handles for operating said valves engaging said steins intermediate said casing for the indicators and the casing` for the valves.

A. gas lock comprising a casing formed and having' a series oit conical valve therein and bored out zig-zag passages connecting said seats. a series of conicai plug valves respectivel;7 engaging said seats and ported a continuous uni ico mounted on said stems, a casing i'or enclosing said indicators provided With a transparent top, and handles engaging said stems intermediate said indicator casing and said valve casing, for the purpose described.

1l. A gas lock comprising a casing formed from a solid piece of metal having a zigza Jassaoe therethrough and a detachable. f3

bearing against lthe shouldered portions of'l said detachable cover and said valves respeet'ively,v means for moving said valves and ineans for indicating their open p0- sitions.

5. A gas lock comprising a casing formed from a solid piece' of Inetal and' having 4a zig-zag passage therethrough, said passage being i'orrned by a plurality of intersecting bored out passages, a cover detachably secured to said casing and provided with apertu therein7 a series oi' plug valves in said casing for obstructing said Zig-Zag" passage, each valve being ported to open communication with said passage when properly set; springs in said apertures and bearing againstlsaid plug valves to hold the saine`Y properly positioned,I means for; moving 'said valves, and nieans'for' indicating their open position. y l
